"Unfortunately we had a bad game against Korea and that could come back and bite us in the bum. We need the Dutch to beat Australia and then it's down to our game against the Aussies and goal difference."
With no shortage of motivation, the Black Sticks were on form today from the opening whistle.
The Kiwis opened the scoring in just the fifth minute after Sophie Cocks deflected an Anita Punt drag flick past the goalkeeper.
Japan solidified their defence following the goal and the score line remained 1-0 to the Black Sticks at halftime.
But three minutes into the second half Punt was in the spotlight again when she rocketed a penalty corner flick into the top of the goal.
The momentum continued and Katie Glynn knocked a reverse shot past the keeper just one minute later to give the Black Sticks a 3-0 buffer.
Japan scored after a bizarre series of events saw the Kiwis away on a fast break before being called back for a Japanese referral for a suspected foot in the circle.
With a decision not clear a bully was called which Japan chose to contest rather than pass the ball back to the Kiwis which is the generally accepted choice.
The Black Sticks lifted their intensity after the goal and finished strongly with Punt scoring a well-worked field goal on the reverse stick to seal the result.
